Awesome Talk Jim! I was really excited to see Elmish.XamarinForms!
I also enjoyed your Open FSharp talk about how you and your co-worker got F# into a production app. My favorite line in there was, "if you can't get permission do it anyway". I also like to introduce new technologies without permission because its easier to show than to explain the benefits.
I believe the F# Xamarin.Forms template is still missing in Visual Studio 2017. If you work with that team maybe you could suggest they add it.
I think showing off all your gear for travel was pretty good. I think it would be helpful to know where you got your thin long hdmi and flat ethernet cables. My favorite thing was the Anker charger, and the battery pack though. If I could find a battery pack that isn't bulky and fits in a pocket I'd probably carry that all the time. Keep up the videos. I'm a big MS DEV SHOW fan too.
